In this study, energy, environment and enviroeconomic analyses are applied to the turbofan engine used in aviation industry. The CO2 emissions of the turbofan engine are calculated and cost of the CO2 emissions for a daily period are evaluated. The energy efficiencies of the overall turbofan engine system, high pressure turbine, low pressure turbine and the combustion chamber are found as 19.7%, 26.2%, 29.2% and 90%, respectively. The CO2 emissions releasing in a day are calculated as 358.9 tonCO(2)/day, while the CO2 emissions price in a day are calculated as 5742.52 US$/day for the turbofan engine. Also, 3.35 kg carbon dioxide is released into the air as a result of 1 kg of kerosene burning. Environmental and the enviroeconomic results of this study can be useful for developing environmentally sustainable turbofan engines as well as for researches and designers in aviation industry.
